'SPECIFICATION forming part of Letters Patent No. 689,072, dated December 17, 1901.

Application filed May 31,1901. Serial Nd; 62,478. (No model.)

To all whom, t may concern:

Be it known that I, ARTHUR FEATHnRsToN- HAUGH, a citizen of the United States of America, residing at Chicago, in the county of Cook 5 and State of Illinois, have invented certain new and useful Improvements in Roller-Bearings, of which the following is a description.

My invention belongs to that class of antifriction devices in which a series of rollers are 1o interposed between the movable parts to reduce the friction.

The object of my invention is to produce a more simple, effective, and durable device than is now available for the purpose stated.

T o this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described, and more particularly pointed ont in the claims.

In the drawings, wherein like reference-letters indicate like or corresponding parts, Figure 1 is a longitudinal section through a carriage-hub equipped with myimproved device. Fig. 2 is a transverse section in line 2 2 of 25 Fig. 1 Fig. 3 is a similar section in line 3 3 of Fig. l. Fig. 4 is an end elevation of the adjustingrings in one position. Fig. 5 is a longitudinal section of the same. Fig. 6 is an end elevation of the rings in another position;

3o Fig. 7 is a longitudinal section of the same,

and Fig. S is a view of one of the cage-rings.

In the drawings I have shown my improvement as applied to a carriage-hub in which the hub carrying the roller-bearing rotates 3 5 about a iXed axle or shaft. It is obvious,

however, that my improvement is equally applicable to all kinds of bearings, as well to those in which the shaft rotates in the bearings as in the form shown in the drawings.

4o As shown in the drawings, A represents an ordinary carriage-hub provided with an inner in'closing shell B.

C C, dre., are rings arranged edge to edge within the shell and are provided with conv 45' ically-formed center openings, which when the rings are in position extend in the same general direction. One end of the column of rings bears against an abutmenuas C', thus maintaining the column in a relatively xed 5o position within the shell B.

D D are compressible rings, which may be opened upon one side, as shown, and which have conical eXteriors corresponding to the interiors of the rings C.

E E are cage-rings maintained in position between the large rings D D', as shown.

G G are rollers maintained in position in the cage-rings by pivots g, which retain the rollers in proper relative position to one another. One end of the column of rings-as, for example, the enlarged ring D2-rests against lthe resilient member H, which in this case is a coiled spring.

K is an adjusting-ring bearing against the outer end of the column of rings D.

L is the adjusting-nut, provided with a screw-thread connection with the shell B. By screwing up the nut L the column of rings D will be pressed inward, moving longitudinally within the rings C, thus reducing the diameter of the inner rings D, which is permitted by reason of the opening in the rings at d. (See Figs. 4, 5, 6, and 7.) By this means the shaft-space inclosed by the circle of rollers D may be adjusted to compensate for wear and slight variation in the size of shafting used. As the cage-rings E are also split and carried with the rings D, it is obvious that the diameter ofthe circle inclosed by the rollers will be reduced, as set forth. The relative positions of the rings C and D are clearly shown in Figs. 4, 5, 6, and 7.

M is the axle or shaft, as the case may be.

As shown in the drawings, N is the bur holding the hub upon the aXle, and O C are ball-bearings which take the end thrust, and thus help to reduce the friction.

It is obvious that my improvement is not limited to carriage or other vehicle hubs, but may also be used in all eases where there is a part rotating upon another. Thus it is adapted for reducing friction of shafting within bearings and in all similar constructions. Thus While I have shown in my drawings a carriage-hub I do not wish to be understood as limiting myself in that respect.

In the preferred form the rollers G are spaced from one another, as shown in Fig. 2, to reduce friction. It is immaterial which col-` umn of rings is longitudinally movable to adjust the parts orwhether both are movable for this purpose. It is also obvious that any suit- IOD able means may be employed to thus adjust the two, the method shown being preferred.

Having thusdescribed my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Aroller-bearing comprising an inclosing shell, a plurality of outer rings arranged edge to edge within the shell and provided with conically-formed center openings extending in the same general direction, in combination with a plurality of compressible inner rings provided with corresponding conical exteriors arranged edge to edge and partially nested in the outer rings, a series of rollers inclosed by the inner rings forming a shaftbearing, means for maintaining the rollers in their relative positions, and means for moving the two columns of rings relatively upon one another to regulate the size of the shaftopening inclosed by the rollers, substantially as described.
